Open up AirMap. Take a look. There are 4 airports that really restrict your flying ability and the strip is off limits for a 1000 reasons mostly because it's less than a mile from mccarren airport. The strip itself has 1000's of people. Even all the golf areas are within LAS airspace.
Red rock is not off limits I found out. It's not a national park. It's a national conversation area. Drones are allowed in most of it. Just don't be THAT guy who disrupts people's enjoyment of a relatively quiet experience.
Also temps outdoors are gonna be in mid teens again so your flight time might be cut short. Especially if you're using an iPad or tablet.
Lake mead is technically off limits as well
